FRANK HARLEY, OF WASHINGTON, KANSAS.

ATMOSPHERIC CHURN.

SPECIFICATION forming part of 4Letters Patent No. 362,373, dated May 3, 51887.

` Application filed February 19, 1887. Serial No. 229,238. (No model.)

To all whom it may concern:

Be it known that l, FRANK FARLEY, a citizen of the United States, residing at Wash` 1 ington, in the county of Vashington and State of Kansas, have invented certain new and use- "ful Improvements in Atmospheric Ohurnsg .gitudinal section through the churn.

and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying draw-'ings,and to letters of reference marked thereon,which form a part of this specification.

Like letters -refer to the same parts throughout the several views.

My invention relates to that class of churns in which air is injected through the cream for the purpose of agitating and breaking up the butter-globules.

' The object of the invention is to produce a churn which may he cheaply constructed and in which is combined the principles employed in the ordinary atmospheric churn with those of the dasher-ohurn, in the manner hereinafter described. l I am thus enabled to produce better results than have heretofore been attained. in the manufacture of butter. l To this end, and to such others as the invention may relate, the same consists in the peculiar combinationsand in the novel construction, arrangement7 and adaptation of parts, all

vas more fully hereinafter' described, shown in the drawings, and particularly pointed out in the claims.

Referring tothe drawings, Figure 1 is a side elevation of a churn constructed in accordance with my invention. Fig. 2 is a vertical lon- Figs. 3 and 4 are details. f

Referring to the details of the drawings, A represents the body of the churn; B, the cover, constructed in two sections, B B2, as shown, and provided with the usual air-vents, a a.

G is a bellows, which is supported upon the uprights D, directly over and at a suitable distance above the rear portion of the churn-body. The air-discharge pipe E extends from the bottom of the bellows downward into the churnbody, and has its outlet near the bottom of the v same. l

F is the operating-lever, which ishinged at the rear end of the churn-body, as showinI G is a link or rod connecting the top of the bellows with the upper end of the dasher-stem G. The upper end of the flasher-stem is pivotally connected to the operating -lever F within the slot b. The dasher-stem is provided at its lower end with a cross-bar, F, the ends of which fit within the vertical guide-slots c c, which are formed within the inner walls of the churn-body.

H H are wings,which may be of either wood or metal, and are hinged to the lower side of the cross-bar F and upon opposite sides thereof. The wing H is provided with an opening, d, for the passageof the discharge-pipe E.

Strips easecured upon the inner faces of l the side walls of the churn, serve to regulate,

in a measure, the upward throw of the dasher, and thus prevent possible damage to the bellows from too violent upwardl movements of the operating-lever.

. From the foregoing description the opera` tion of the churn will be at once understood. By forcing the operating-lever downward, the air contained in the bellows is forced downward through the pipe E, where it escapesinto the lower portion of the churn beneath the wings H H. The same downward movement of the lever forces the dasher-stem downward, carrying with it the cross-bar F', to which are hinged the wings H H. The wings are, bythe downward movement, caused to open out into a horizontal position, thus suddenly compressing the air beneath and forcing the same upward through the body of the cream within the churn. The wings being solid, with the exception of the opening d, the air is forced to escape around the outer edges of the churn,

I attach importance to my crossb'ar F,whieh serves not only as a support for the dashers, but also, in connection with the grooves c, serves as a guide for the dasher-stem. Importance is also attached to the manner of connecting the operating-lever, dasher-stem, and

IOO

bellows, giving me a direct connection and a positivesimultaneous movement of the dashorstem and bellows, and in this connection the stops e are important, preventing injury to the bellows by a too powerful or sudden upward movement of the dasher-stem.

Having thus described my invention and set forth its merits, what I claim to be new, and desire to secure by Letters Patent, is-

1. In a churn, the combination, with the churn-body, the dasher-stem, and the bellows communicating directly with the interior of the said body, of the operating-lever having a slot within which the dasher-stem is pivoted, and the link G, attached at one end to t-heupper end of the daslier-stem and the other` end attached to the bellows, substantially as described.

2. The combination, with the churn-body formed with guides c and the flasher-stem, of the bellows supported above said body, the cross-bar F, secured to said stein and guided by said guides, the dasliers H H,hinged to said cross-har and one provided with a slot, d, the

vertical pipe E, communicating with said bellows and extending into the churn-body with its free end passed through said slot, and means for operating said dasher-stem and bellows, substantially as described.

3. The combination, with the churn-body, the reciprocating dasher-stem, hinged dashers carried thereby, and the bellows communicating with said churn-body, of the lever F, fulcrumed at one end on said churn-body and provided with slot b substantially in the center of its length, within which slot the upper end ofthe flasher-stem is pivoted, the link G, connecting said stem directly with the bellows, and the strips e within said body, serving as stops, substantially as and for the purpose described.

In testimony whereof I affix my signature in presence of two witnesses.

FRANK FARLEY.
